Diffusion of carbon in substitutionaSfy alloyed austenite

摘要

It is well known that the diffusion coefficient D of carbon in austenite varies with the concentration of carbon [1,2]. In a previous analysis, it was demon-strated that a theory due to Siller and McLellan [3,4] can adequately explain the experimental data for Fe-C alloys in the austenitic condition over a wide range of concentration and temperature.
